What is an HMO mortgage?

Buy-to-let mortgages for HMO properties are simply referred to as HMO mortgages. These are mortgages used to purchase an HMO, with the property used as security for the debt.

HMO (House in Multiple Occupation), is a term used by the government to explain:

“A property rented out to at least three people who are not from one household but share things like the bathroom and kitchen.”

The key term here is: ‘Household’. A household is classed as a property used by couples who are married/living together, families or relatives. These do not fall under HMO rules.

Another term often used to describe this type of property is a ‘house share’. This could be students renting one house or workers sharing a house. An example of this could be a four-bed house, where each bedroom has its own door lock and is let to a single tenant. The individual letting rooms are not self-contained meaning they all share a kitchen and bathroom, unlike a flat.

Typical HMOs could include:

  • Bedsits
  • Shared housing
  • Hostels
  • Privately run halls of residence
  • Employee housing

The difference between buy-to-let & HMO

A buy-to-let or single let property is, for example, a house rented out to a single-family unit. An HMO property, however, is let to multiple (three or more) tenants, such as students. This will require an HMO mortgage.

There are advantages and disadvantages to both. A single buy-to-let is simpler to manage but if the tenant moves out, there could be a rental void. As this type of house has several tenants, this void is less likely.

Are these houses a good investment?

Landlords are attracted as they often offer greater rental yields and, subject to a strong location, it can be easier to find tenants. Students, companies and housing associations are all good examples of likely tenants. Tenants are attracted to these type of properties as they can be far more affordable. They are popular in high-value rental areas as the cost is shared by more paying residents.

Take the example of an HMO property used to provide housing temporary workers (e.g. contractors). Good rents will likely be received and there will be a steady stream of tenants. Even better, the company may pay the rent regardless of whether they have put a worker in there or not. This saves you the hassle of having to find new tenants every time someone moves out.

As the structure of the tenancies differs from that of a simple buy-to-let, these mortgages can be a little more complex to arrange. An experienced adviser can make the process hassle-free.

Is an HMO licence required?

Any property deemed a ‘Large HMO’ will need to have a valid licence in place. According to the UK government website, an HMO is considered to be large if both of the following apply:

  • It is let to five or more separate tenants forming more than one household.
  • Tenants all share a bathroom, kitchen and toilet.

Different councils may have different rules regarding licencing. Therefore, even if your property does not fall into the above description, it is worth contacting the local authority to find out.

You must have a separate licence for each ‘house share’ property you run. This usually lasts for five years and must be renewed before it runs out.

When applying, the council will want to make sure:

  • You or your letting agent are deemed to be ‘fit and proper’ with no criminal convictions or breaches of the landlord code of practice etc.
  • The property is a suitable size and facilities are adequate for the number of tenants.

The council will also require:

  • That you send them an up-to-date gas safety certificate every year.
  • Have adequate, maintained smoke alarms fitted.
  • Provide them with safety certificates for electrical appliances.

The lender may also want a copy of any licences. If you don’t have a licence, they may look to either accept an undertaking from you to obtain one or, evidence that you have applied. If your property requires a licence, you can apply for one on the government’s website. If your application is declined, in most circumstances, you can appeal the decision.

Typically, this needs to be done within 28 days of the decision and there may be a fee to pay.

Can I convert a property into an HMO?

This can be done, subject to planning permission. However, it’s worth bearing in mind that not all lenders will allow this.

We have access to HMO conversion products which are ideal for this scenario, regardless of the level of refurbishment involved. The interest rate will be higher whilst the refurbishment work is carried out, but a lower rate will be available when the work is complete. This is often referred to as a bridge-to-let product.

In some cases, we can arrange a property refurbishment loan whilst having the long-term mortgage pre-approved and ready to complete. In these circumstances, you can move to the cheaper long-term lending as soon as the work is complete.

What is Article 4 direction?

An Article 4 Direction is a restriction imposed by the local planning authority to control the use of permitted development rights.

Before Article 4 came into effect, you could change the use of a property from C3 family home to C4 HMO without consent. Now, if the property is in an Article 4 area, you must apply for consent to change the use.

How will my HMO be valued?

The main two variants of valuation are as follows:

  • Bricks and Mortar Valuation: This is the standard method of valuation for most types of HMO property. This type of valuation is simply of the building only and assuming it is vacant.
  • Commercial Valuation or Investment Valuation: This is the value based on the overall investment or business rather than just the building itself.

Many people assume that when a property is converted, it instantly increases in value because of the rental yield. However, this isn’t strictly correct. For a standard residential house converted to an HMO, most mortgage providers will base the LTV (Loan to Value) ratio against the bricks and mortar value. This is something worth considering when looking to invest.

Take, for example, a street full of four-bed terraced houses all valued at around £100,000. All of them are either owner-occupied or let to single-family units on ASTs (Assured Short-hold Tenancies). If one of those properties was converted to a four-bed HMO, at a cost of £10,000, it would be unlikely to now value up at £180,000 for mortgage purposes. Smaller HMO’s are treated much the same as a standard buy to let property.

To obtain an investment or yield-based valuation, in most cases, you need a minimum of 6 letting rooms. This isn’t guaranteed, however, this will be subject to the valuers’ comments and due-diligence. The valuer would be looking at things like Article 4, location and how many other HMO’s there are within the area. The cost of commercial valuation can also be higher when compared to a bricks and mortar valuation.

HMO mortgage lenders

With this type of property becoming more and more popular, there are mortgage lenders available to suit almost everybody. Each one will have their own criteria. But with hundreds of products available, finding the best product to suit you should be straightforward.

The available lenders can largely be broken down into 3 main types:

  • High street banks/vanilla buy to let lenders: These lenders will usually offer the best deals but will have strict criteria. They will usually have a maximum of 4 rooms with tight rules around the leases and the applicants’ experience.
  • Specialist HMO lenders: These will look at slightly more complex applications and larger HMOs. Some lenders will have a specialist division, whilst being a largely vanilla buy to let lender. You may pay a slightly higher rate but will benefit from more flexible criteria.
  • Commercial mortgage lenders: These lenders are ideal for those with complex HMOs, those lacking experience or those with quirks that won’t fit other lenders. You will pay a higher rate than with either of the above lenders but will benefit from the most flexible criteria.

How much will it cost?

The cost of your finance can depend heavily depending on the following:

  • Whether the mortgage is repayment or interest only
  • For repayment mortgages, the term chosen (how many years you pay back over)
  • Whether your preferred deals have fixed or variable interest rates
  • Take a look at the latest deals on our comparison page and then try out our mortgage calculator to work out the monthly repayment. You must consider all fees when choosing a product, such as early repayment charges, to ensure you save as much money as possible.

    What information will I have to provide?

    The lender will usually want to know the following information:

    • The property – location, number of letting rooms
    • Your background in letting property
    • Sourcing tenants – will the tenants be sourced directly, or through an agency?
    • What demographic will your tenants likely be?
    • Licensing – will the property be a multi-let or licensed HMO?
    • The business plan – expected rental income, covering rental voids etc.
    • Personal income/expenditure/assets/liabilities
    • Your credit rating
    • How you will repay/borrow – personally, or through a company?

    In addition, you will usually be expected to provide the following information:

    • Proof of ID & residency
    • Proof of income
    • Copies of leases (where the property is already let)

    Can I get a limited company HMO mortgage?

    There are a wide range of lenders out there who will consider applications, so we usually have a solution available. We can fund applications from the following:

    • Individuals
    • Partnerships
    • LLPs
    • Limited companies
    • Expats
    • Overseas applicants investing in UK property

    How can I access get the best mortgage rates?

    As with other types of lending, the best deals are reserved for the lowest risk applications. Low-risk applications are generally those with a strong rental cover, experienced applicants with no bad credit and suitable security.

    By filling out our online enquiry form, you can have a conversation with an adviser. We work to secure you the lowest mortgage rates, arrangement fees and guide you through to mortgage process to save you money.
    Whether you’re looking for equity release for further HMO purchases, or to purchase your first investment property, we can have a conversation to understand your needs.

    The benefits of using a specialist HMO mortgage broker

    The advantage of using a whole-of-market broker is that you can access all providers through one online enquiry. An experienced adviser will get in touch to gather key information about what you’re looking to do, and about you as a borrower, before finding the best deals to suit your circumstances.

    Don’t be concerned about being asked a lot of questions when applying. The more information available, the more aware of an applicant’s circumstances and needs. This will help you get the best deal.
    The only real disadvantage is that you may have to pay a fee for this service. You should ask the adviser how much this fee is during the initial conversation.

    As a common rule, we don’t charge broker fees for mortgages above £150,000. However, for smaller mortgages, this will be considered on a case by case basis. We aren’t tied to any one lender and are totally unbiased. Our only interest is in securing the best deal for you.

    We have built up strong links over the years which help when guiding an application through to completion. We are able to search the whole market quickly to secure you the best terms available whilst offering you honest advice and market-leading rates.
